Geum plant named ‘Fire Storm’

ABSTRACT

A new and distinct  Geum  plant named ‘Fire Storm’ characterized by orange flower color, large, double flowers, a compact, upright habit, long bloom time, and excellent vigor.

Botanical designation: Geum hybrid.

Variety denomination: ‘Fire Storm’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geum plant given the name ‘Fire Storm’. Geum is in the family Rosaceae. The new cultivar is a whole plant mutation found in a cultivated area, more specifically, a greenhouse in Canby, Oreg.

Compared to Geum ‘Fireball’ (unpatented), the new cultivar is much more compact. Both are sterile and do not produce seeds.

Compared to Geum ‘Totally Tangerine’ (U.S. Plant Pat. No. 22,041), the new cultivar has double flowers rather than single.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fire Storm’. These characteristics in combination distinguish ‘Fire Storm’ as a new and distinct cultivar:

-   -   1. orange flower color,     -   2. large, double flowers,     -   3. compact, upright habit,     -   4. long bloom time, and     -   5. and excellent vigor.

This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
